Reading from two devices at the same time

Hello,

I am considering duplicating the main board on my device, and using two USB links, one to a system USB port and the other to an add-on card such as a PCMCIA card or PCI card.

Are there any complications I should know of with reading Bulk data continuously on both of these ports at the same time? My guess is that as long as they don't exceed the bandwidth of the main bus everything should be fine?

I'm thinking I will need separate threads for each process which will look almost identical, runnning at the same time. Has this been done/tested before?

The one USB port is providing more than enough bandwidth, but i'm considering using two USB links as it is cheaper than overcoming a memory problem I am having on the one device.

Thanks,
Juan
